midi footpedal code

WordPress won’t let me easily include code in comments, so I’ve posted it as a page. This code is used to control my Echoplex Digital Pro by sending specific midi CC messages, but these can easily be adapted to send other messages, PC, CC etc. Although it works, it’s nowhere near finished and there’s probably a much better way of doing the same thing. I’m also running out of arduino pins, so multiplexing will be required to add more buttons or leds. The learning curve never seems to flatten out ;(
